I have just purchased a Nexus 7 (2013) and it auto updated to android to 4.3 as I was setting up. Unfortunately USB OTG now does not run. I purchased the Nexus 7 for it's OTG feature. I've done a factory reset but it still loads 4.3 Is there any way I can go back to 4.2.2 - which does support OTG on the Nexus 7

  • A factory reset will only reset "to factory settings", not "to factory software". That is, basically it simply wipes your /data and /cache partitions, but it doesn't touch /system. See also the factory-settings tag-wiki. – Izzy Aug 12 '13 at 12:42
  • Did you try with 4.4.2 (KitKat+). I have had no issues with my Nexus 7 (2013). Can you provide more details of what you are actually trying to achieve? (not just use USB-OTG) – david6 Feb 26 '14 at 8:49

I don't think the Nexus 7 (2013) ever had Android 4.2. I was going to suggest flashing a factory image but the only one available is Android 4.3 which suggests it's not possible.

As the other answers have suggested you will probably need to root to get the USB OTG functionality you are after.

    The Nexus-7 (2013) 'razor' was released with 4.3 (JSS15Q). There is no official 4.2 or earlier versions. – david6 Feb 26 '14 at 8:47
  • Wow, that factory image list can be handy also if someone wants to downgrade from Lollipop to KitKat! Thanks! – Csaba Toth Feb 21 '15 at 7:21

If you are reverting to 4.2 only for USB OTG feature, then I would suggest you not.

I am using a rooted Nexus 7 (2012) from v4.1 - v4.3 and could say from that experience that it has to be rooted for the OTG features to run. Since that's missing from your question I assume that you are not rooted when you had 4.3.

The apps Stickmount and USB OTG Helper needs root privilege to run successfully.

  • You don't need to root Android devices to use some OTG functionality, such as the ability to plug in a mouse or keyboard. – user5506 Aug 12 '13 at 12:43
  • My apologies. I had a myopic view that USB OTG is about storage devices only. – Narayanan Aug 12 '13 at 12:58

You're going to have to revert by installing a custom recovery, and then flashing whichever ROM you require yourself. It's not difficult but needs to be handled very carefully (ie getting the correct rom, and following all the steps exactly) to avoid damaging your device. You may find it hard to claim repairs under warranty if you do this, depending on the laws where you live.
